OrCAD 16.6
To boost overall PCB design productivity, OrCAD Capture, OrCAD
Capture CIS, PSpice® A/D, and PSpice Advanced Analysis include
numerous new features and enhancements that increase each tool’s
usability, configurability, and performance.
OrCAD Capture has been integrated with OrCAD PCB SI to deliver a
new bi-directional schematic entry/signal integrity flow for
electrical engineers. The 16.6 release also extends the Tcl
programming capability and apps to PSpice, allowing users to
customize their simulations and environment.
OrCAD Capture and Capture CIS
Capture – PCB SI integration and flow: With product integration
comes a new bi-directional schematic entry/signal integrity flow
that allows electrical engineers to explore circuit topologies,
develop constraints, and analyze signal integrity.
Quick-place for common components: A new menu, Place >PSpice
Component, enables quick-place for commonly used schematic or
simulation components. The menu items list of components is
user-configurable and has been pre-populated with PSpice simulation
devices (passive, discrete, sources, digital).
User-configurable menus and toolbars: Menus, toolbars, and icons
in OrCAD Capture, PSpice Advanced Analysis, and Model Editor can
now be customized. This makes it possible to run any Tcl method or
script from the menus.
Enhancements to the Find function: The Find function now allows
searches for parts by value of a given property
(e.g. Property Name=Value) or use of a regular expression as the
search string. For example, to search for components with
designators starting with C or R and followed by any number between
2 and 9, use the search string Part Reference=(C|R)[2-9].
NetGroup enhancements: The NetGroup use model is now aligned
with the Bus use model for intuitiveness and consistency.
Enhancements areas include: assign a NetGroup to a Bus, reorder
pins in an unnamed NetGroup, add and remove pins from a NetGroup,
visible NetGroup references, and find NetGroup references.

CIS performance increase: The overall performance for CIS
operations, especially when dealing with very large databases or
queries, has been significantly improved.
Tcl customization for CIS Explorer: CIS Explorer can be
custom-configured with user-definable actions and capabilities.
(For example, customized part placement checks can disable
placement of an EOL part or provide a warning if part procurement
has a long lead time). Query result rows can also be customized.
(For example, rows can be highlighted blue for recommended parts or
red for parts not recommended or allowed.)
PSpice A/D and Advanced Analysis
Advanced control options: Numerous advanced convergence and
simulation control options/parameters have been added or exposed,
giving users greater control over simulation and convergence. These
options include: bias-point convergence, voltage limiting,
worst-case deviations, max-time step control, pseudo transient, and
relative tolerance.
Probe .dat upgrade to 64-bit precision: PSpice now generates
64-bit data precision in the .dat file output. This ensures higher
precision compared to the 32-bit .dat file data from previous
releases. (As an example, in previous releases, when a very small
amplitude voltage is superimposed on a large voltage, the resulting
voltage lost its resolution in a 32-bit .dat file.)
UNDO support for captured netlists: Netlisting to PSpice now
preserves UNDO, making it easier to make iterations and modify
parameters, components, and connectivity.
Enhanced IBIS support: The PSpice IBIS translator now supports
IBIS models up to version 5.0 (not including AMI) for use in
simulations.
Multi-core engine support: Enhancements to multi-core support
and I/O read-write provide significant performance improvements.
Focused performance enhancements, especially for large designs or
designs with complex model instances (MOSFETS, BJT), also boost
performance.
Encryption enhancements: Upgraded model encryption now includes
256-bit (AES) encryption support.
Tcl-based customization: Advanced Analysis, simulation, and .dat
file access can be custom-configured with user-definable actions
and capabilities. This enables an environment that can be
customized to specific flows and needs, and allows users to
leverage enhanced features and design capabilities

3D and ECAD-MCAD in OrCAD 16.6
Cadence® OrCAD® 16.6 has added full 3D visualization and
incremental MCAD-ECAD collaboration capabilities that utilize two
common industry data formats; STEP and IDX.
Eventually, almost every PCB must be housed inside something.
Utilizing STEP and IDX, OrCAD PCB allows the import and
visualization of physical and mechanical elements, such as
enclosures, to help ensure the board is designed correctly with
respect to mechanical require-ments. Design data— including the
ability to collaborate on changes through a managed, bidirectional
change-review and approval process—can also be shared between
electrical and mechanical teams..
Bidirectional ECAD-MCAD Collaboration
The IDX format and supporting CAD tool interfaces provide
capabilities that allow changes between electrical and mechanical
teams to be previewed graphically before accepting or rejecting
incremental changes. The benefit of this flow is that design teams
can more closely collab-orate on changes, consider effects on the
other, make changes early and as often as needed, and remain in
sync throughout the design process.
Accurate 3D Visualization
STEP models for components give designers the ability to see a
realistic three-dimensional representation of the design in the
context of the enclosure and/or other
physical limitations that must be accounted for. Within the 3D
visualization environment, it is easy to perform visual clearance
checks to detect conflicts or issues early on and ensure PCB
components and mechanical elements have the proper fit prior to
manufacture.
“The very first STEP model that I tested (a shield generated by
our mechanical department), I found to be placed 180 degrees out,“
said Dave Elder, PCB design manager at Tait Radio. “This would have
been very difficult to detect without a 3D view. This has allowed
us to avoid a potential pitfall, not to mention a sum of money in
rework.”
Cadence OrCAD 16.6 Available Now
The IDX interface/flow for OrCAD PCB is available in the
16.6 base release and the STEP capabilities are available in the
16.6 Quarterly Update Release #2.

Expanded Tcl/HTML5 Capability
The Cadence® OrCAD® 16.6 release enables deeper access to design
data along with greater control over GUI and feature manipulation,
providing new levels of customization capabilities for Capture and
now PSpice®. The open architecture platform continues to evolve
with support for hybrid applications that utilize JavaScript and
HTML5. Custom flows and external application integration, such as
HTML-based corporate or web services, can greatly extend the OrCAD
design environment.
PSpice has also been enhanced with a Tcl/HTML5 programming
infrastructure that allows customization of simulations with
parameters/algorithms and .DAT file output. This enables you to
enhance the simulation environment for specific flows, needs, or
control, and allows you to leverage external data or conditions to
enhance design simulations.
Tcl/HTML5 customization has also been extended to new user
configurable areas of both Capture and PSpice, including
Tcl/HTML5-based features, GUI menus and toolbars, and CIS.
User-configurable menus and toolbars: Menus, toolbars, and icons
in OrCAD Capture, PSpice Advanced Analysis, and Model Editor can
now be customized. This makes it possible to run any Tcl/HTML5
method or script from the menus.
Quick-place for common simulation components: A new menu, Place
->PSpice Component, enables quick-place for commonly used
schematic or simulation components. The menu items list of
components is user-configurable and has been pre-populated with
common PSpice simulation devices (passive, discrete, sources,
digital).
Action customization for CIS Explorer: CIS Explorer can be
custom-configured with user-definable actions and capabilities.
(For example, customized part placement checks can disable
placement of an EOL part or provide a warning if part procurement
has a long lead time). Query result rows can also be customized.
(For example, rows can be highlighted blue for recommended parts or
red for parts not recommended or not allowed.)
Custom design rule check (DRC): User-specific schematic and
circuit checks can be created and added to the Capture DRC
routines. Several examples include checks for hanging wires, device
pin mismatches, overlapping wires, reference prefix mismatches,
port-pin mismatches, and shorted discrete parts.

New Marketplace Apps
Since the launch of Marketplace, the number of OrCAD apps has
steadily grown with additions from Cadence and our partners. New
productivity apps since the 16.6 release include datasheet display
at a component level, logo scaling for PCB, and Capture-cloud
connector.
One of the newest productivity apps, PSpice Modeling app, takes
advantage of the expanded Tcl capabilities and HTML5 in the 16.6
release; support for rapid simulation modeling development
applications.
The new PSpice Modeling app significantly reduces the time and
effort to develop components and models needed for simulation
during design entry. Models are created with user-input
parameters—as from a datasheet—and a schematic component is
automatically placed and associated with the newly created model
without having to leave the OrCAD Capture canvas. The modeling
application also automatically manages the simulation profile
configuration without needing library set up for simulation.
OrCAD Capture Marketplace
Launched in the fall of 2011 as part of the OrCAD 16.5 release,
OrCAD Capture Marketplace delivers an integrated, online resource
with specialized content and tools for OrCAD Capture and PCB Editor
users. Component information, simulation models, educational media,
and add-on applications (apps) provide easily assessable design
content along with the ability to customize and extend the OrCAD
design flow and environment.
Enabling an extensible and customizable design environment,
OrCAD’s open architecture platform incorporates a highly integrated
Tcl/HTML5 programming infrastructure that allows the creation or
enhancement of features, functionality, design capabilities, and
flows. This development environment is available to customers and
partners to quickly develop solutions for their specific needs.
Created and delivered as downloadable apps through OrCAD
Marketplace, new features, functionality, or design capabilities
are available from Cadence or our partners.
